[Emerson]

An A3 driver's license can be upgraded to an A1 license, provided the applicant already holds an A3, B1, or B2 license and meets certain conditions. According to the "Regulations on the Application and Use of Motor Vehicle Driver's Licenses" and the "New Regulations on Streamlining Administration, Delegating Power, and Improving Services," applicants for upgrading to a large bus driving license must meet one of the following conditions: 1. Have held a city bus or medium-sized bus driving license for at least two years; 2. Have held a large truck driving license for at least three years; 3. Have held a tractor driving license for at least one year. In addition to meeting one of the above conditions, applicants must not have accumulated 12 or more penalty points in any of the three most recent scoring cycles before applying. What are the situations where upgrading to an A1 license is not allowed?

Being held equally or more responsible for a traffic accident resulting in death; 2. Driving under the influence of alcohol; 3. Having a driver's license revoked or canceled within the past ten years. Conditions for upgrading to an A1 license: 1. Height: At least 155 cm; 2.
